Mx1100 Serial BTR for Remex Manual - Memex Automation

8. A CNC error occurs shortly after pressing “Cycle Start”.
Try removing the CR (carriage return) characters from the
program. Some controls only accept “pure” ISO or EIA code,
which does not contain CR characters. Also try changing BTR
jumper A7 in case it’s a matter of ISO / EIA format mismatch.
9. The control generates a Tape Vertical (TV) alarm.
Tape Vertical checking was a way that controls verified the
accuracy of the program code they read in through the Tape
Reader. It is usually an option and does not apply when you are
using a BTR. Turn this option off in the control’s parameters.
10. The control generates a Tape Horizontal (TH) alarm.
Tape Horizontal is equivalent to Even parity. Use Even parity
when sending the programs from the terminal or PC. Also see
Notes 7 and 8 above – jumper A4 and/or A7 may resolve this.
11. The Power LED lights but the STATUS LED doesn’t flash.
Check the supply voltage to the BTR. If using a 5VDC supply and
it is less than 4.6VDC, the BTR may actually be protecting itself
from under-voltage. Find a better 5V supply, or switch to 24V (see
Note 1 “b”) or use the screw-down terminal in the bottom left
corner with a supply of 7 to 24VDC. Always be sure to set up the
power jumpers correctly (see Notes 1 and 2).
12. Other machine errors:
Ensure that you have added in the proper tape codes at the
beginning and/or end of your program. Some machines require that
you have a % sign as the first and/or last character in your
program. Check your CNC Operator’s Manual for any termination
characters that may be required.
13. What if the BTR “Locks Up”
Near the upper left corner of the BTR are the four pins labelled
RESET and LOAD. Of those four pins, the top two are the reset
pins. Momentarily shorting the two RESET pins by touching them
with a metal object such as a screwdriver or coin (while the power
is on) will reset the BTR and make the STATUS LED flash. This
action is the equivalent of pressing the reset button on a PC. This
should not have to be done on a regular basis, but, as with anything
electronic, lockup can happen.
